Risk management is critical in decision-making, and mean-variance (MV) trade-off is one of the most common criteria. However, in reinforcement learning (RL) under a dynamic environment, MV control is not as easy as that under a static environment owing to computational difficulties. For MV...

One of the important future issues is how agriculture production can meet the future demand increase due to the population and the income growth. Global warming would give both positive and negative impacts on them. Agriculture is often expected to supply biofuels to meet the growing...

Achieving a sustainable consumption and production pattern is one of the United Nation's sustainable development goals for 2030. To achieve this, it is necessary to consider the environmental burden from a product life cycle and the quality of life of the consumer. In this study, a systematic...
